Revision and psychometric evaluation of the Chinese version of Depletion Sensitivity Scale / 中国心理卫生杂志

ABSTRACT

Objective:To validate the Chinese Version of Depletion Sensitivity Scale (DSS) and test its validity and reliability.Methods:A sample of 499 postgraduates coming from a university in Beijing was investigated with preliminary questionnaire,249 of them were assessed for exploratory factor analysis(EFA) and 250 of them were assessed for confirmatory factor analysis (CFA) and testing of validity and reliability.The criterion validity was tested with the Self-Regulatory Fatigue Scale (SRF-S),Dual-Mode of Self-Control Scale (DMSC-S) and Adolescent Self-rating Life Events Check-list (ASLEC).Totally 280 students were retested for test-retest reliability with 2 week interval.Results:DSS was composed of 8 items in two factors,which were cognitive factor and behavioral factor.The two factors explained 60.7％ of the variances.The confirmatory factor analysis identified a two factor model (x2/df=4.18,RMSEA =0.09,NFI =0.95,NNFI =0.94,CFI =0.96,IFI =0.96,GFI =0.96,SRMR =0.05).The scores of depletion sensitivity were positively correlated with the scores of cognitive fatigue,behavioral fatigue,emotional fatigue poor control,punished,loss,relationship pressure and adaption problem (r =0.13-0.55,Ps ＜0.001).The Cronbach α coefficients were 0.80 for the total questionnaire and 0.79 and 0.73 for the two factors.The test-retest reliability were 0.52 for the total questionnaire and 0.46 and 0.58 for the two factors.Conclusion:It suggests that the Chinese version of Depletion Sensitivity Scale (DSS) is reliable and valid enough to be applicable to measure the depletion sensitivity of Chinese graduate students.
